Exploring Patterns and Sequences with Decimals

This video tutorial covers patterns and sequences with decimals, explaining how to identify and apply pattern rules using addition and subtraction. It demonstrates extending sequences, finding missing terms, and solving practical problems involving money. The tutorial emphasizes the importance of comparing terms to determine consistent rules and highlights the use of mixed operations in complex patterns.
